Fungus Treatment and moisture barrier install for the property $2200, plus another $500 quarterly.   

It backs to rt 59 and is very loud and I heard there is issues with the stucco and moisture that has got behind the walls.

Give your tenants the EPA "A Brief Guide to Mold, Moisture, and Your Home" booklet.

Be gentle about living next door to people that are paying you.

One $20K expense (reskin interior, moisture damage, HVAC, foundation issues) and you've got an average deal or worse.

There are some holes in the outer wall that we'll fix and will hopefully stop future water intrusion...but I don't know the climate well enough to know what is "normal moisture" in this region...Do these seem like "medium" priorities?

Quote from @Ben Bechard: Mold requires a water source to grow, so there's clearly still a moisture issue down there.

This can allow moisture to get into the uncured paint film allowing certain components to come to the surface when the moisture evaporates, causing surface staining and possible adhesion problems.I don't know how experience you are with rehabs, but 6 weeks are only doable if you stick to paint and carpet and don't do any rough in electrical, plumbing and drywall work.

You should seriously consider getting dehumidifer(s) and fans running to get that moisture out of the house..
